Answer

A has 3 electrons B has 6 electrons C has 4 electrons D has 8 electrons

Work Step by Step

Since each drop must contain an integral (or whole) number of electrons, the charge of each drop must be a whole-number multiple of the electron’s charge. By this logic, the maximum charge whose multiples are found in the drops is $-1.6 \times 10^{-9}$ z. The charge on the electron = $-1.6 \times 10^{-9}$ z. Hence, number of electrons in drop A = 3 number of electrons in drop B = 6 number of electrons in drop C = 4 number of electrons in drop D = 8
